Manufacturing & profiles
Technology
Corrugated and tile-profile metal roofing sheets formed from PPGI coils.
Overview
Our focus is formed metal roofing — conventional corrugated sheets and tile-profile sheets — produced from pre-painted galvanized steel (PPGI).
Corrugated metal roofing sheets is the product category term — not the company brand. The public brand is AL-RASIKH.
Roll-forming process overview
Educational overview of how continuous metal roofing sheets are typically formed. Exact equipment counts, speeds, and tolerances are published only when verified for a specific product or factory record.
Decoiling and leveling
Steel coil is decoiled and leveled so the strip feeds smoothly into the forming line.
Progressive roll forming
Sequential forming rolls shape corrugation or tile geometry while protecting coated surfaces.
Cut to length
Formed sheet is cut to the ordered length for the project.
Inspection and stacking
Sheets are checked against the agreed specification and prepared for handling.

Overview
- Metal sheetA continuous thin metal sheet — corrugated or tile-profile — for roofing applications.
- Formed profileWave or tile geometry affects stiffness and appearance — use verified factory values only when published on a product.
- Overall vs coverage widthOverall width is the full sheet; effective coverage width accounts for side overlap in installation.
- Surface & coatingPPGI (pre-painted galvanized steel) is the principal material stated in the company profile. Other finishes appear only when documented on a product record.
- Overlap & installationCorrect side and end overlaps maintain weather performance on garages, warehouses, and agricultural buildings.
- Typical applicationsResidential, commercial, warehouse, workshop, industrial, and agricultural roofing — subject to agreed specifications.
Sheet dimensions and coatings are shown on individual product pages.
